I want to use it but people around me always forgot that I am gaijin. I changed my hair color into beige recently and my co workers said “wow you look like a foreigner!” I told them “but I AM a foreigner!!!” So many times they wont believe me when i said i dont know about some rules or habit and they will think i was just joking even tho i am really serious. Sometimes it is great for them to treat me like one of them but I wanna use gaijin pass/smash too!
